While ideologically that makes sense, the advent of the internet doesn't just magically solve the realities of content distribution. Sure there are systemic issues with parties not wanting to move the needle, but there are real and valid issues that prevent this sort of thing from happening.
Let me give a simple example. We have a studio 'Sorny' that creates a show. They want to distribute it all over the world. However, there isn't a single company with distribution capabilities across the globe. Now enter 'Webflix'. They have a service that includes the US, UK, Canada, and Japan. Sorny would love to have it available everywhere, but they can't ask Webflix to give them reasonable value for worldwide distribution for two reasons. One, Webflix doesn't directly offer their service everywhere and will only pay for the areas they intend to directly offer the given content. Two, they literally can't afford the world-wide distribution valuation. Webflix is a growing business, but they do not have infinite reserves. They need to grow revenue by slowly expanding to different markets, increasing the userbase in each region. Once they have sufficient subscribers in a given region they can then add more and more content there.
See where this is going?
Now move back to Sorny. They then want to offer this content in other regions. First problem is contract negotiations take time. You can't expect multiple companies of different sizes to get things done at the same time. Worse, Sorny's negotiating power is negatively impacted because these new distributors argue that people in their region are using VPN's to access Webflix, and they can't guarantee the number of users Sorny is claiming in their valuation. Now negotiations further stall.
Then we consider that Sorny has also contracted said content for usage on TV. It has all the same issues only worse. Sorny isn't in control of when that content is shown. In each region it's up to these distributors / networks. Since TV is still the big game versus streaming, Sorny has to place precedence with them and therefore contracting streaming rights is further stalled until after the networks rights are over or they pass on the content.
Now think of movies. There is then multiple other layers of distribution and rights that have to be considered.
etc
etc
etc
Basically until there is a single company that can literally distribute globally, this mess is going to continue. And said company would have to actually offer reasonable valuations, otherwise Sorny will continue to go with separate distributors. For this single company to have that kind of money, they'd actually have to be well established in nearly all regions in order to have sufficient revenue.
It's really a clusterfuck
